I am sorry to hear that Melissa, (┬┬﹏┬┬)
I passed my PMP on the 1st try. I think that your plan will work. I spent five weeks and made Rita, my best friend. The resources I used were Rita (book & audiobook) and PMBOK. I read through Rita's book 2 1/2 times, and I used the PMBOK as a reference for a simple explanation. Rita may be wordy, but she will tell you how the pieces of the project fit together.
The crazy part is that it did not start making sense until my final week. At that point, I told myself, I understand these terms, but it did not know how PMBOK wants a project to run. It all "clicked" when I remembered the 49 processes. So, my primary advice would be to know/learn the 49 processes. You should know all of them AND how they work together. After learning the 49 processes and understanding that in a defined project plan, for the most part, things are meant to go in order (Initiate > Plan > Execute > Monitor & Control > Close). Also, the knowledge areas are generally done in columns. There was one YouTube video (How to Memorize the 49 Processes from the PMBOK 6th Edition Process Chart). It helped me a lot to remember the 49 processes. The acronym of the knowledge areas from the video, "I Saw Six Cars Quickly Rip Carol's Right Passenger Side" changed everything for me! Knowing knowledge areas acronym helped me build my graph during the PMP exam. In addition, it came in handy when I saw these style of questions: "What should the project manager do?"; "What should the project manager do first/next?"; "What is the best course of action?"; "What tool or technique does the project manager use in this scenario?"; "What PM technique is described in this situation?"; "What should the project manager have done differently to avoid this situation?" I would go down the chart to verify I was right.
Also, remember what Rita said, do not think of the projects you have been on, but think of the perfect PMBOK project unless the test tells you there was something wrong with the project. However, caveat, YMMV.
Thanks for your humility. Best of luck, Melissa. (●'◡'●)
